Blender Cycles: How to make a Clay Render (no AO / no Lights)

Hi everybody. Sometimes, when you are creating a complex scene, you need a method to get a simple render of your objects, without taking account into materials, lights, backgrounds or environments. This is known as a clay render (see the image below). In some render engines you have an option to do this. But in Cycles you don't have it.

The color should be RGB (0.8, 0.8, 0.8) or similar, and the roughness is 1.0. This use the Oren-Nayard algorithm for the diffuse shader. The Lambertian algorithm produces brighter colors and darker shadows, and it is used with roughness equal to 0.0.

If you want to assign one material to all the objects in your scene, you can create it for one object, select this, then press A (select all objects, but the first is the active object), and go to menu Object >> Make Links >> Materials.

You don't need to set lamps, meshlights or check Ambient Occlusion in your World settings. If you prefer another background color just change the blue color in that Background node. The white background node has a color value of RGB (1.0,1.0,1.0).
